WIT/V6535 E6 FRANK REESE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO REESE MANUFACTURING COMPANY, OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF MINNESOTA.

WINDOW-SCREEN.

To all whom it may concern:

Be it known that I, FRANK Rnnsn, a citizen of the United States, residing at Minneapolis, in theicounty of Hennepin and State of Minnesota, have invented certain new and useful lmprovemei'its in \Vindow-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide 'an extremely simple, cheap, efficient and durable metallic window screen, and to such ends. generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

Particularly, the invention resides in the improved construction of the metallic f mile of the window screen whereby the wire cloth or screen proper may be easily replaced.

In the acconmanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

leferring to the drawings:

Figure 1 is a plan view of the improved screen with some parts broken away, showing the frame. however. of an exaggerated width in proportion to the size of the wire cloth;

Fig. 2 is an enlarged section taken on the line m m of Fig. 1;

Fig. 3 is a fragmentary view showing one corner portion of the wire cloth: and

Fig. 4 is a view corresponding to Fig. 2, but illustrating a slight modification thereof. or addition thereto.

The wire cloth or screen proper is indicated by the numeral 1. This cloth is of substantially a rectangular form and of a size adapting it to be bent on a broken line marked a on Fig. 3. To facilitate the bending on the said line a, the corners of the screen are preferably cut oil, substantially as shown at Z) on Fig. 3.

The metallic frame is made up of two members 2 and 3. The member 3 is angular or approximately L-shaped in cross section, and the member 2 is of like form, except that it is provided in line with its face web with a projecting clamping flange 2. Both frames 2 and 3, in outline or plan view are rectangular, and the laterally projecting Specification of Letters Patent. Patefited Feb. 20, 1912'; Application filed May e, 1916. Serial No. 95,750.

flange of the frame member 2 is adapted to be telescoped within the laterally projecting flange of the frame member 2 with sufficient clearance to permit the marginal portion of the wire cloth 1 that is beyond the bending line (1. to be clamp'g'd between theingi as shown in Fig. 2. The two forms, when assembled with the marginal portion of the wire cloth clamped between them, as stated, are rigidly, but dctachably held together, as shown, by means of screws 4 passed through perforations in the lateral flanges of the member 3 and screwed into the lateral flanges of the member 2.

By this arrangement, the wire cloth will be very firmly held in place and the clamping action is further increased by a clamping flange 2 which presses the wire cloth against the edge of the lateral flange of the frame member 3. Obviously, the cloth will be very quickly and easily applied to the frame and if it should become worn or torn, may be easily removed and replaced by a new wire cloth.

The construction illustrated in Fig. 4 is like that shown in Figs. 1 and 2, but the channel between the parallel flanges of the frame members 1 and 2 is filled in by channel-shaped metallic strips 5 which may be held in position by friction or by additional securing means, such as solder or welding.

The frame members 2 and 3 are each formed with four bars. and these bars preferably have mitered ends rigidly united by welding. brazing or similar means.

The screen frame described is not only very strong. durable. convenient and eflicicnt. but may be made at comparatively small cost.

Vhat I claim is:

1. The combination with two rigid and col'nplete rectangular metal frames having integral laterally projecting clamping flanges telescoped, one into the other with but slight clearance, said frames having approximately parallel outstanding flanges forming the sides of the complete frame, ofa wire cloth or screen proper, having its marginal portion bent and clamped between the telescoped flanges of the two frames, the said two frames being separable as entireties.

2. The combination with two rigid and complete rectangular metal frames having integral laterally projecting clamping flanges telescoped, one into the other with but slight clearance, said frames having approximately parallel outstanding flanges forming the sides of the complete frame, of a wire cloth or screen proper, having its marginal portion bent and clamped between the telescoped flanges of the two frames, the said two frames being separable as entireties, and metallic fastening devices passed through the telescoped clamping flanges of said frames and through the laterally bent edge portions of said screen and holding the said three elements against separation.

3. The combination with two rigid complete rectangular metal frames that are L- shaped in cross section and having their integral laterally projecting clamping-flanges telescoped, one into the other with slight clearance, the parallel outstanding flanges of said frames affording open channels, of a w re cloth or screen proper having its marglnal portion bent and clamped between the telescoped flanges of said frames, the said two frames being separable as entireties.

In test1mony whereof I affix my signature 1n presence of two witnesses.

FRANK REESE. Witnesses:

F. D. MERCHANT, HARRY D. Kimonn.
